'1 '0 all whom 'it may concern:

Be it known that I, TIMOTHY F. MINA- HAN, a citizen of the United States, resi din at Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Dampening-Machines; and to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

i This invention relates to improvements in dampening and stretching machines for collars.

The object of the invention is to provide a machine of this character by means of which the collars are dampened by pressing or forcing moisture into the same thus expediting this operation and enabling the dampening, stretching and ironing of the collars to be. performed in one continuous operation.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed outHin the appended claim.

tn the accompanying drawings, Figure 1 is a side view of a collar dampening and stretching machine constructed in accordance with the invention showing in dotted lines a part of an ironing machine; Fig. 2 is a. vertical longitudinal sectional view of the same; Fig. 3 is a vertical transverse sectional view taken through one pair of dampening rolls and the moisture conducting roll engaged therewith; Fig. 4 is a detail perspective view of one of the moisture conducting rolls.

wardly and hold the upper rolls in forcible project beyond the I do declare thefollowing d are provi ed with engagement with the lower rolls. The springs 5 are provided. with tension adjusting screws ti whereby the pressure of the springs on the boxes4 and the consequent pressure ofthe upper rolls on the lower rolls is regulated.- The journals of the rolls- 8 sides of the frame-and intermeshing gears 7 and the gears of the upper rolls of each pair are operatively connected to other by small gear pinions 8. The gears of the lower rolls of the last and intermediate pairs of rolls are connected together by a gear pinion 9.

By thus connecting the rolls together, they will be driven in the proper direction, as

indicated by the arrows in Fig. 2 of the drawings. The shaft of the pinion '9 is pr0- vided with a drive pulley 10 which is operatively connected to any suitable power for driving the machine.

Mounted in suitable bearings 11 in the side pieces. of the frame 1, below the bearings of the lower rolls 3, are moisture conveying rolls 12 which are corru ated longitudinally and are held in form lo engagement with the lower roll 3 by pressure 7 springs 13 arranged below the bearings 11. The tension of the springs is adjusted by screws 14 whereby the ressure of the rolls 12 against the lower ro Is 3 is adjusted and the amount of water thus applied to the rolls .is regulated. The rolls 12 are driven by frictional contact with the rolls 3.

Arranged below each of the moisture conducting rolls 12 and supported in any suitable manner, are water holding receptacles 15 which are preferably in the form of shallow pans or trays in which the lower portions of the rolls 12 turn.

. rolls 3 are padded, as shown Referring more particularly to the drawping the same with a suitable fabric or abings. 1 denotes my improved dampening machine which consists of a suitable sup- The dampening at 16, by wrapsorbent material whereby the moisture from the rolls 12 will be absorbed by the lower rolls engaged therewith and by said lower rolls will be pressed or forced into the collars when assed between the pairs of dampening .rol s. By applying the moisture to the lower rolls only and passing the collars between the rolls with the outer side of the collar uppermost, simply the underside of the collar will be dampened so that when a the collars are ironed, the shiny or greasy appearance usually found on the seams of the collars, after ironing, is obviated. By

thus forcing or crushing the moisture into the collars, they are sufficiently dampened after passing through the pairs of dampening rolls to permit the same to be immediately stretched and ironed, thus enabling the dampening, stretching and ironing of the collars tobe performed. in one contmuous operation.

In connection with the dampening mechanism, I employ a stretching mechanism consisting of a pair of padded rolls 17 which are here shown as being suitably mounted in a portion of the side pieces of the frame 1 of the dampening machine. The lower roll 17 is revolubly mounted in stationary bearings, while the upper roll is mounted in movable bearings and is held in forcible engagement with the lower roll by pressure springs 18 having adjusting screws 19 by means of which the pressure of the upper roll against the lower roll is regulated. The journals of the rolls 17 are provided ontheir outer ends with intermeshing gears 20 and motion is imparted to said rolls by a train of gears 21- connecting with the driving gears of the ironing rolls 22, shown in dotted lines in the drawings. The gears of the train 21 are of such size and are soarranged that the speed of the stretching rolls will be slower than that of the ironing rolls thus retarding the movement of the collars and causing the same to be stretched by the first pair of ironing rolls which pull or draw the collars from between the stretchin" rolls.

I rom the foregomg descriptiomtaken in connection with the accompanying drawings,

the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may beresorted to without departing from the principle or sacrificing any of the advantages of the invention, as defined in the appended claim.

Having thus described I claim is:

In combination, a frame, a plurality of pairs of coiiperating padded pressure rollers, one of each pair of rollers haviag movable bearings mounted to reciprocate in .the frame, springs to engage said Hearings to force the rollers mounted therein" toward the opposite rollers, the opposite roller of each pair being mounted in stationary bearings carried in the frame, slidable bearings mounted in the frame,.liquid tanks carried on said slidable bearings, corrugated dampening rollers mounted in said slidin bea-rings and positioned within said tanIrs, and meansto force the dampening rollers into engagement with the rollers in the station ary bearings.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

my invention, what TIMOTHY F. MINAHAN.
